PIPE-COUPLING.

Specification of Letters Patent.

To allfwhom t concern:

Be it known that I, JACOB L. BRosoHART, a citizen of thel United States,res1d1ng at Trenton, in the county of Grundy, State of Missouri, have invented a new and useful Pipe-Coupling; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as -will enable vothers skilled in Jthe art to which it appertains to make and use the'same.

'This invention vrelatesfto the art of cous' plings, and particularly to a `type especially adapted for use in connection with train orsteam lines of passenger or freight trains.- I

Heretofore, when a train line vbeeonies broken at any location the car having the severed or broken portion of the train line. becomes dead, in sofar as the proper operation of the air brakes are concerned, consequently it is necessary to set the car out on $100 every 24; hours, and to move a train after engine failure, which results in the air brakes being inoperative, it is exceedingly dangerous particularly going down grade. ln caseof car failure, or should a car become a non-air car, the expense infinally getting the carto its terminal wouldapproximately or members, one or bothends of which may be $7 or $8 every 24 hours.v 1

Therefore, in general it is the aim ofthe present invention to o-vercome these -forego-v Y ing difficulties and disadvantages, by pro-Y viding an emergency' devi-ceV of this kind, whereby the train vor steam line of the train may be temporarily repaired at any locationit may become broken, so that the train may continue on to its terminal, where proper permanent repairs may be made.'

Further, it is the aim to equip each and every train with one or more of the present emergency couplings, with which a train line, either at the angle cock or-'the T, or at the usual or common coupling of thetrain line, or at anylocation in the cross-over connection, may be easily and quickly temporarily repaired, the repairs requiring little ratentmi May 2o, 1919.

or no time, to put the train orsteam line into Y service.

Specifically, la l'further object of the inventionl is to provide an improved, simple, eficientV and practical compound coupling, which may be used single or double, for uniting the adj acent' ends of a brokenpipe or for uniting twio sections of piping either of the same or different diameters.

A further-object of the invention is to providean emergency coupling having exl ansible--inembers or rin s and ackinvs"A P g e the ackinof beinO constructed of an 'su1t-" able material preferably rubber.

Should the steam lline become broken, it may be'easily and quickly repairedby eniployment of the-emergency coupling, by substituting steam resisting gaskets in lieu of the rubbergaskets. 1 However,- should the occasion require, a section of a hose gasket may be cut oult,thereby allowing the gasket to be used in-lieu of the rubber packing, in

order to facilitate the repair to the steam line. f Y

A furtherobject of the invention is to yprovide a Ycoupling of this kind including metallic packingmembers, which may be eX panded or contracted in order to bulge, jam o-r expand the rubber or steam resisting packings, in order to render the coupling efficiently secure whereby a non-air car .mayv be allowed: to remain yin its proper place in the train, thereby allowing the train to Y reach its destination without setting the non-air car to the rear. Y

A further object of the invention is to provide metallic expansible packing rings be expanded, to lock the coupling secure.

1M furtherobject of the invention is to provide sectional metallic expansible rings,

and means for holding the sections in their i I proper positions when expanded.

Further it is-the aim to improve simplify and render more practical and useful the structure of coupling, set forth, illustrated and claimed in the application of Jacob L. l Broschart, .for a patent on a pipe coupling, y

filed March 8, 1918, Serial No. 221,163, which is matured into patent issued 15th day of October, 1918, Patent No. 1,281,905.

In practical ii'elds the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprise further features Fig. 3^isV a lview in side elevation of the train line, illustrating three different `breaks in theline as having Vbeen repaired `by use-of the emergency coupling, one `break being made .inthe cross over connection.V

Referring more especially to thedrawings 1 designates that portion Vof a train line-car-V pling 4 at the locations 5 and 6. The train Y line may become broken adjacent Ieither end ofthe T 9, as at W and 8. The cross over connection of the train line may also become broken, either at 10, 11, '12, 13 and 14. It is obvious that should thetrain line be,- come broken at` any one of theselocations, the same may 'bel easily and quickly teinporarily repaired by any of the couplings shown in the other gures, for instance asV shown in Figs.. 3 .and 4.

Referring to Figs. 2, 3 and 4, it is be noted 4that the coupling comprises a pipe or tubular section 15 exteriorly threaded throughout its length, and in Fig. .4 165 and j 17 denote the broken parts of rtlietrain line.

Threaded on the `pipeor tubular section 15 adjacent :both ends thereof are collars or .rings 18 and 19, which are locked'against rotation by 4the ykeys 20. Surrounding the pipe' or tubular section v115 and adj acentsaid i collars 19 are .eXpansible vpacking members 21 and 22. Also surrounding .the tubular Vor pipe section are the metallic bands 23 and 24 the adjacent ends ofwhich Vare tapered as shown .at 25 and 26.

These vmetallic bands Vor rings vare arranged adjacent the'vv expansible rubber packings so that when they are forced vtoward the packings, said packings 4will be expanded toward Vand in contact frictionally with :the inner wall of the broken train line sections 16 and 17.

Also threaded .upon the tubular or pipe f section 15 are'jamming or locking sleeves27 and 28, the adjacent ends-of which are provided with nut heads 29. .The Vother ends of the sleeves aretapered as shown at v30.

Interpo'sedfbetween the jamming or rlocking sleeves 27 'and'28 andthe metallic bands or v rings-23V and 24, and surrounding the pipe` or. tubular section 15 areV rings. 31 and 32, which may be anyk suitable'sh'ape, prefer- Yably as shown, andA are providedV with spring arms 33. The ends of thearms 33 are flared orltu-rncdx .outwardly into -sharpcned corners .or edges 34, adapted to bite iii-o into the inner wallof the train line sections Y `16 and In order to unite the adjacent .severed ends of the train line sections 16 rubber packings 21 and 22 causing them to expand frictionall-y in contact with the inner walls of the train line sections 1-6 and Y 17. AtV the same time that the metallicA bands 23 and 24 are forced toward and jamming the packings, the spring arms 33 of 'the rings 31 and 32 will be expanded causing their sharpened edges 34 to bite into the inner wall of the train line sections 16- and -17 thereby locking the coupling parts secure.l modified forms of metallic expansible'rings or members are illustrated. In Figs. 6, 7 i

and 8 the expansible metallic rings 35 are circular, and each consists of two semicircular sections 36, which surround the' kpipe or tubular section 15.

The opposite edges of each ring'35 are turned or flared outwardly, and are substantially sharp, so

as to bite into the inner wall ofthe train line sections 16 and 17, as shown at 37'. The sections 36 of the ring 35 are provided'with grooves 38 for thev reception of expansible split round ringsy 39, to holdv the sections36 in place as they are expanded. In Figs. 6, 7 and 8 the tapered portions 30 ofthe jamming or lock-ing sleeves 27 and 28 'sub- 40`are split :diagonally as shown at 41, so as to expand or contract, as a result of looseningl or tighteningup the jamming o-r locking sleeves 27 and 28. These metallic ex-l pansion rings or bands 40' have their oppo- .site 'ends provided with sharpened outllared edges 42, to bite into the inner Wall of the train line sections 16 and 17.

prises an outer casing 43, one end of which has an internal shoulderV 44, and adjacent the yshoulder is a ring 45 having spring arms 46`provide'd with end sharp edges 47, which are'designed to bite rinto the outer wall of the coupling sleeve l48, which unites the pipe sections 49 and 50, by means of the threaded connections 51 and 52. 'Arranged adjacent the sharpened end edges of the arms 46 is a metallic ring 53, so beveled as to force the sharpened .edges into the coupling sleeve. Also surrounding the coupling sleeve 48 and located within the case is a metallic ring 54,'

which is also beveled similar to the ring 53, and interposed between the rings 53 and 54 is a rubber expansible packing 55, which by means of the bevels of the rings 53 and 54 is contracted inwardly 'toward andfin frictional contact with lthe sleeve 48. Additional metallic, rings 56 and'57 are arranged In Figs.' 6, 7, 8, 9 and 10,V

In Figs. 9 and'lO the `metallic expansion rings or bands In Figs. 12 and 13 the coupling com-,

in the casing 43, and which arefalso beveled.A

Interposed between the rings 56 rand 57 `Yisy v a rubber packing 58, which, owing to the opposed bevels of the rings 56 and 57,pis contracted toward andk in Icontact with-the pipe lsection 50. Arranged in the casing 43'` is a metallic ring 59 k,having spring tongues or arms 60, which, by contacting with 'thebevel'of the ring 57, are contracted orA de` flected` inwardly, sov as to bite intothe vpipesection` 50. Surrounding the pipe vsection V50 and threaded into the casing 43V is a jamming or locking sleeve 61, which abuts the ring 59, whereby the spring arms or" tongues 60 may contact with and be deflected'by the bevel of the ring 57.

Y By-screwing the jam! i` ming sleeve, the several rings vmay be forced toward the shoulder 44 thereby contracting the rubber packing members 49 and 50. v'One end of the jamming sleeve 63 has a nut head j 62, and a threaded cavity 63, yinto whichl an inch and a quarter pipe or tube64 of a train line 0f a passenger train is threaded. It is obvious that instead *ofl inserting a pipe -section49 with the coupling sleeve-48 and'a vquarter pipe" 65 of the trai-n line of j the-"passenger train may be inserted-'into thev coupling,- (which is shown inFig. 12) andtelescopically over a yshort pipe section 66, as shown in Fig. 13. vThe spring-arms or tongues 60 have sharpened end-edges 67, in order t0 bite into the pipe section 50 of the trainline.-

Referring to Fig. l of the drawings, it is 99 --into the coupling 'shown in Fig. 12, aninch l to be noted-that should the train line break as at 3 at the left-hand end in Fig. 1, the angle cock 2 may be removed, and an'ordinary elbow 68 coupled to the usual air hose 69 as shown-in Fig. 3. In this case the end V70of the pipe or tubular section 15 is threadi ed into the lock sleeve` 71, while the other end of the emergency coupling, asindicated i 'at 72 is inserted into the portion 73 'ofthe train line, thereby temporarily splicingfthe train line, whereby the trainmay continue tol its' terminal after which permanent re- Should the train lineY break at 5 Vor 6, for instance 5, the opposite rends of the' emergency vcouplenkmay be in- 115 serted into the severedends of the trainline,

as shown clearly at 74 in Fig. 3, and also as shown in Fig.. 4, thereby .temporarily uniting or splicing the train line, `to allow the train to continue to its terminal. Should the cross over connection become broken as at 13, one end 75 as 4shown in Fig. 3 may vbe inserted into the broken parts of the cross over, that is after-removing the cross over valve 76, the auxiliary reservoir 77 and the air cylinder 78. When inserting one end of the coupling'into the cross over connec-` tion as shown in Fig. 3, a cap 7 9 is ,threaded to one end of the tubular or pipe section 15, thereby holding 85% air in the train line.

' tion with the `adjacent ends of a broken train Should a 'break occur in the crossover adj aa centl the vauxiliary reservoir, the cross over valve 76 may be closed, and in this case the coupling would-not be used. Also should "the crossover connection break at 14, .the cross over valve 7 6 may be closed, in which,

irepaired vin the same manner vas whenthe tra-in line is broken either at 5 or G. I-Iowever, should the'cross over connectionbecome brokeneither at 10, 11 or 12, one end of the Acoupling is inserted either lin the tubular legof the T 9L or in the elbowSO, justsuiiiciently to permit one of the eXpansion packing rings 21, or 22 to be expanded intothe broken part of the cross-over connection, that is the broken part .which allowed` to remain in the leg or the elbow, then ythe other end of the coupling is inserted .into the opposite severedY par-tsiof the crosS-overfthereby temporarily repaire The invention `having .been set forthv what is claimed as new and useful is 1.l In an. emergency coupling, thecombinationwith the adjacent ends 0f a broken pipe-,14 ofa pipe section eXteriorly-.threaded throughj out its length, ya lock collar'on each end of j said section, a band surrounding said section and spaced from the collar, and an .eX- pansible -packing between-the band and the collar, a jamming sleeve threaded-on thesection, a ring interposed between the ,sleeve and the band, said ring having eXpansible means adapted to expand tobite into the interior wall'of one of said ends, when the jamming `sleeve is turned h'ome.
